Right, i would like to hear that too. Some one who knows Soekris boards,
polling techniques and drivers interrupt handling could shed some
Anyway, did you try to use brad@ patch to OpenBSD sis driver which try
to use interrupt hold-off ?
If you can't find it in the archive, shot me an email I'll forward you.
I would also like to see test result with OpenBSD 3.8 since the idle
loop fix produced at hackaton didn't go in 3.7 (short time) and probably
it could help in here.
